Abstract:
The electron density fluctuations of CT-6B Tokamak plasma have been studied in detail through the observation of Hα emission intensity by multichannel optical diagnostics. Their various behavior, such as power spectrum, fluctuation level and correlation,have been measured. The experimental results show that some characteristics of density fluctuations are founded in CT-6B Tokamak plasma: the density fluctuation level is about 10%-90% in the radial range r=4-10cm; the point in the range draws, nearer to the edge of plasma the level lecomes higher. A broadband power spectrum is observed at observed points along the plasma radius. There exists a local correlation structure with short correlation time, about 0.2-0.5ms, and short correlation distance , about 0.5-1cm,in the edge of plasma.
